I am really enjoying parts of my new position, last night I received a part with a defect in it, I cut out a cross section of the defect on a bandsaw, put it on a polishing machine, polished the edge of the cross section and used a camera and microscope to get a picture of the defect. The defect was only .05mm acrossed and .01mm high, so at 60X magnification it was MUCH clearer and allowed me to identify the problem.
At 60X magnification you can also see the individual layers that make up the component being examined, Ex. substrate, E-coat, prime, base and clear coat and of course the defect itself. Polishing the edge of the component takes some patience. I had two samples, one I was patient and took my time, and I was able to get a good picture of the defect, the other sample I "manhandled" and destroyed the defect which made it useless, patience is good.
The picture above is magnified approximately 300X allowing the individual layers of material to be seen, YUP! I REALLY like this job!
I'm going to head off for now, that Baptist wiskey is calling me (COFFEE!)
Later for now!
